摘　　要：煤粉的粒度分布是影响煤粉所成物质的物理性质。然而对水煤浆煤粉粒度的测定,是个值得探讨的问题。本文介绍了超声衰减粒度仪测量原理,对比了激光粒度仪和超声衰减粒度仪的特点,并且通过实验说明超声衰减粒度仪在煤粉粒度测定中应用的优势。The particle distribution is the main factor to the performance of substance made of coal. However, the question on the coal particle size determination is always a problem and that is worth to discuss. This paper introduces the principle of ultrasonic attenuation in particle size measurement, contrasts the laser particle size analyzer and ultrasonic attenuation particle size analyzer features. And through experiments indicates that the ultrasonic attenuation particle size analyzer in the determination of the particle size of pulverized coal in coal water slurry application advantage.
